I am a research scientist at the Institute of Physics of the Globe of Strasbourg (IPGS), University of Strasbourg in France, where I work since 2007. I graduated for my PhD at the University of Strasbourg in 2004. My PhD research focused on cryogenic gravimetry applied to the long-period seismic modes and on the elusive translational oscillation of the Earth's inner core. Then I spent 2 years as a JSPS post-doc at the National Astronomical Observatory of Japan in Mizusawa (Oshu-shi), in Tohoku area. I also spent one year at the Royal Observatory of Belgium in Brussels, focusing on planetary rotation. During my JSPS fellowship, I started to look at the observational effect of the coupling of modes due to lateral heterogeneities in the mantle. Particularly, theoretical computations for a three-dimensional heterogeneous rotating elliptic Earth model have shown that the radial fundamental mode 0S0, normally observed only on vertical components, should be present also on horizontal components because of the coupling effect. My research at ERI aims at reducing the atmospheric pressure-induced tilting noise on horizontal seismograms of F-net stations in the long-period seismic band. Such noise reduction would improve the observation of seismic modes and may help to detect for the first time the horizontal component of 0S0. The detection of the non-radial motion of 0S0 is important to determine the reference bulk Q of a reference 1D Earth model.
